Pre Teen bedroom

I have been painting my eldest son's bedroom. Only another 3 walls to go. It's meant to be a roughly painted Union Jack. My Husband asked when I was going to finish it. Hmm maybe the concept needs work.

However I have decided to stick old National Geographic posters on the other wall. It looks good. I am a little short on covers though. I reckon I need 30 and I have at the moment... wait for it...7! Looks like this is going to be a work in progress. What is interesting though is I am using Post it Note glue to stick the covers on there by allowing me to remove them at some unspecified date when the Pre-teen gets bored with them. He may of course never get a full wall of covers. I just subscribed to National Geographic and at this rate it will only take 4 years.
